MACHINE FOR TREATING HIDES OR SKINS.

Specification of Letters Patent.

Application filed February 12, 1910.

Patented June 21, 1910.

Serial No. 543,560.

To all whom it may concern:

Be it known that I, WILLIAM EVANS, a citizen of the United States,residing at the city of Philadelphia, in the county of Philadelphia andState of Pennsylvania, have invented certain new and useful Improvementsin Machines for Treating Hides or Skins, of which the following is aspecification.

My invention relates to certain improvements in a machine for fleshingor slating hides or skins by the use interchangeably of a knife oriieshing cylinder or of a slating cylinder in conjunction with anendless adjustable conveyer-apron when provided with a grip-roller forholding or positioning the hide or skin while acted upon in its travel,corresponding in diameter to that of the drive-roller for saidconveyer-apron, and which rollers are positively geared together, torevolve at the same speed and thus to insure better control of the feedand correspondingly improved fleshing or slating action upon the skin orhide and also economy in wear throughout of the grip-roller in practicaluse in such type of machines; and my invention further relates to theconstructive arrangement of the grip-roller for such a type of machine,which in diameter corresponds to that of the drive-roller, for anendless conveyer-apron, the said griproller having certain surfaceformations, as helical grooves broken by circular grooves in spacedrelationship, arranged transversely to the helical grooves, whereby isprovided a means due to such arrangement, for the uniform and evenholding of the hide or skin in its travel through the machine.

My invention consists rst, in a machine for treating hides or skinshaving a griproller in diameter corresponding to the drive-roller for anendless adjustable conveyor-apron arranged to be manually shifted intothe path of a rotating fleshing or slating cylinder; and second, agrip-roller of the character dened.

The nature, characteristic features and scope of my present inventionwill be more fully understood from the following description taken inconnection with the accompanying drawings forming part hereof, in which-Figure 1, is a vertical central sectional view through a machine forltreating hides or skins, embodying particularly main features of my saidinvention. Fig. 2, is a. front elevational view in broken section of somuch of a machine as serves to illustrate my said invention, inoperative relationship, for the performance of the actions upon a hideor skin, as hereinbefore defined, and also showing the grip-rollerprovided with helical grooves, broken by circular grooves in spacedrelationship and arranged transversely to the helical grooves thereof;and Fi 3, is a vertical sectional view of the said grip-roller on theline w, of Fig. 2.

Referring to the drawings, 4 is a side standard of the machine.

5 is a mechanism for operating a treadle 6.

7 is a feed table adjustably connected with standards 4.

8 is an endless conveyer-apron mounted on rollers 9, 10, 11, as shown,in an operative position. The roller 9 is the drive-roller.

10 is the shiftable roller actuated by means of the treadle-mechanismwithin the standards 4, and 11 is the stationary guideroller of theconveyer-apron 8.

12 is either a rotary leshing or slating cylinder, journaled in thestandards 4, and operated in any well understood manner. A familiarexample, of a type of fleshing or knife cylinder that may be used isshown and described in United States Letters Patent granted to me, underdate of September 25th, 1894, No. 526,387.

13, is the grip-roller journaled in the standards 4, and on a journal 16thereof is mounted a gear 14, arranged to mesh with a complemental gear15, on a journal 17, of the apron drive-roller 9. Both of said gearsbeing arranged beyond one of the standards 4. The journal 16, carries alarge gear-wheel 18, which meshes with a smaller gear 19, and bothoperative from the main driving shaft 20. This shaft carries loose andfast pulleys 21 and 22, as clearly illustrated in Fig. 2. Thedrive-roller 9, and grip-roller 13, are each of the same diameter andgeared to each other so that they do travel at the same-rate of speedand thereby to uniformly or evenly hold the hide or skin in its travelthrough the machine, when the apron 8, is brought into an operativeposition, as shown in Fig. 1; and also to economize in wear of thegriproller 13, and thus to insure better leshing or slating action ofthe hide or skin, owing to the unison action as to speed of the saidgrip-roller 13, with respect to that of the drive-roller 9, of the apron8, carrying the hide or Skin thi-@agb the machine, aided particularly bythe particular surface formations of the grip-roller 13, as clearlyshownin Figs. 2 and 3. The surface formations consist of helical groovesbroken by circular tions are `given to the ghide or skin the flesh-ingo-rsslating thereof. ,The defined :arrangement 'rof roller 13, -enablesparticularly economical :results being obtained, .because ofthe uniformWear ofthe parts of the -machine,due tto the unison of speed asarranged, fof the said 4Working parts ofthe machine.I .1 f

Havingthusdescribed-fthe nature and Vobjects ofmy linventiomavhat Iclaim as .new and :desire to :secure by Letters Patent is 1. In amachine :provided Witha conveyerapron and-driveerollen la `grip-roller=in diameter corresponding dio .that of said driveroller, and saidgrip-roller provided With certain grooved formations broken by certaingrooved formations in spaced relationship, oppositely arranged inrespect to each other, to insure thereby, more smooth or even surfaceconditions being given to the hide or skin, substantially as described.

'2. In :a `.machine provided with a conveyerapron and drive-roller, agrip-roller in diameter corresponding to that of said driveroller, andsaid ygrip-roller 2provided with helical grooves broken by-circulargrooves in spaced irelationship, arranged` transversely to :said helicalgrooves, substantially as and for the purposes described.

In Witness whereof, I have hereunto set my rsignature in the presence oftwo subscribing Witnesses.
